Geometry Syllabus

Geometry

“Geo-” means “earth” and “-metry” means measure. Much of geometry is about measuring, and also about shapes, their properties and relationships between them. There are many opportunities to explore and investigate geometric concepts and relationships using concrete manipulatives. A

hands-on visual approach is taken. The role of proofs in understanding geometry is clarified.

Comparisons between inductive and deductive reasoning are made. Skills taught are closely related with other branches of mathematics such and algebra and trigonometry. Algebra I is a prerequisite for this course. To be successful in geometry, knowledge of solving equations, sketching graphs, factoring equations, and simplifying radicals is integral.
